DRAFT STOP FOR VESTIBULE AND OTHER DOORS Filed March l5, 1950 PatentedDec. 22, 1931 UNITED STATES PATENT OFFICE ROBERT JOHN GASKIN AN D WESLEYEUGENE MAYBEE, OF TORONTO, ONTARIO, CANADA DRAFT STOP FOR VESTIBULE ANDOTHER DOORS Application led March 15, 1930. Serial No. 436,229.

Our invention relates to improvements in draft stops for vestibule andother doors, and the obj ect of the invention is to devise simple meanswhich will eiectually prevent any draft passing through the clearancespace between the bottom of the door and the floor, and yet will notinterfere or retard the movement of the door during opening or closingand yet, at the same time, is self-adjustable to readily pass over theedge of a carpet or other similar obstruction as the door is opened orclosed, and it consists essentially oi the arrangement and constructionof parts allV as hereinafter more particularly eX- plained.

F 1 is a face elevation of the door looking from the inside and showingour draft stop applied thereto.

Fig. 2 is an enlarged sectional view through a fragmentary portion ofthe door and our draft stop.

Fig. 3 is a similar View to Fig. 2 looking at the end of the roller ofthe stop.

In the drawings like characters of reference indicate correspondingparts in each figure.

1 indicates a door which is hinged to the frame 2 in the usual manner. 3and 4 are opposing brackets secured to the door adjacent its lower edgeas indicated at 3 and 4X in Figs. 2 and 3. The body ot each bracket- 3and et extends outwardly at right angles to the face of the door.members pivotally mounted at 6 to their respective brackets 3 and 4, thepivot being located intermediate of the length ot each hook member.

The upper end of each hook member is provided with a slot 8 formedconcentric to the centre of the pivot 6X, and 9 is an adjusting screwwhich is threaded in the bracket 3 or 4 and extends through the slottedopening 8 of either of the hook members 6 or` 7, the head of the screwbeing on the inside of such hook member it may be readily gotten at tofree the hook member so that it may swing readily upon its pivot when itis necessary to adjust the same as will hereinafter appear.

The interior hook openings of the hook members 6 or 7 are in the form ofsubstantial- 6 and 7 are hook ly vertical slots 6. 10 is a rollerprovided witha covering 11 formed of carpet or other suitablefabricmaterial. 12 and 13 are pintles extending'from the ends of the roller 10into the slotted openings 6 of the hook members 6 and 7 resting freelytherein so as to permit the roller yhaving free vertical movement.

In order to etfectually form a draft stop the roller 10 would have tocontact not only with the floor but with the inner face of the door 1,the contact between the periphery of the roller and the face of the doorbeing adjusted by the screw 9 so that there is not suiicient friction toret-ard the free revolving motion of the roller, and yet prevent anypassage of air upward between the contacting surfaces.

In opening and closing the door it will be readily seen that the rollertravelling inward or outward will readily pass over the edge of a carpetsuch as indicated at 14 in Fig. 2, the pintles 12 and 13 rising upwardin the slots 6. In closing the door, the weight of the roller whenpassing from the carpet on to the ioor carries the roller downward intothe normal position thereby forming a tight closure in all positions.

What we claim as our invention is:

1. A draft stop comprising a pair of right angular brackets adapted tobe secured to the inner face of a door and Vadjacent each vertical edgethereof, a hook lever pivotally mounted upon each bracket intermediateof its length each lever being provided with a slotted opening at itsupper end concentric to its pivot and an adjusting screw carried by eachbracket and extending through the slotted opening of each hook member soas to secure the same in any position to which it may be adjusted, and aroller provided with end pintles freely carried in the hooks of the hookbrackets and having its exterior periphery contacting simultaneouslywith the floor and the adjacent face of the door.

2. A draft stop comprising a pair ot' brackets secured to the inner faceof the door adjacent each vertical edge thereof, a lever pivotallymounted upon each bracket intermediate ot its length, means foradjusting the lever upon its pvot to any desired position, a roller, andmeans for removably mounting the ends of the roller in the lower ends ofthe levers so as to simultaneously Contact With the floor and with thedoor.
